Zusammenfassung: | A memory device includes a sense amplifier coupled to a first read voltage during a first phase of a read operation and a second read voltage during a second phase of the read operation. A first and second bias voltages are based on the first and second read voltages and corresponding current on a bit line. A first capacitor includes a terminal coupled to the first and second bias voltages. A first amplifier includes an input coupled to another terminal of the first capacitor and another input coupled to a common mode voltage during the first phase and to a reference voltage during the second phase. A second capacitor includes a terminal coupled to an output of the first amplifier. A second amplifier includes an inverting input coupled to another terminal of the second capacitor and another input coupled to a common mode voltage. |
